Table Of Contents

In case you haven’t been paying attention to recent developments, the cordless impact wrench is slowly becoming the favorite tool of professional mechanics and hobbyists alike. If you happen to think that a regular cordless drill is all you need, we can safely state that you are missing out on one of the most effective inventions of the past few years. Unlike the drills that can only create an inline torque, impact wrenches have the unique capacity to generate rotational torque. This makes them significantly more effective and impactful than any other tool. Keep reading as we delve into every aspect of these machines and introduce you to the best cordless impact wrench for the money, best cordless impact wrench for automotive and more.

Factors to consider before buying

Like all power tools, impact wrenches can be quite confusing for a beginner. This is further compounded by the manufacturers’ propensity to overhype their products and throw a lot of superfluous and confusing specs at the customer. Fortunately, we have made things extremely simple for you by reducing all the variables down to these few straightforward attributes:

The torque

When it comes to any type of cordless drill, this factor is really the be all and end all. While the minimum power will vary from project to project, it is advisable to get a unit that can produce a decent amount of torque. Even if you think that you don’t need that much power, you should stay on the side of caution and get the most powerful model that you can afford. You should also keep in mind that some elements can negatively impact the working torque of the unit, namely rust, and weathering.

Efficient design

The design of a cordless impact wrench isn’t merely a matter of aesthetics. In fact, the quality of the design has a direct impact on the overall functionality and performance of the power tool. The best cordless impact wrenches are often ergonomically designed in a way that ensures better power efficiency, more comfortable grip, fewer vibrations, and an overall improved level of performance. The quality of the handle is especially critical since it plays a significant role in determining the tool’s ability to operate for an extended period of time. The handle should be made from durable materials and must be designed to fit the contours of your hands.

The size of the drive

This is also an important factor that goes unnoticed by most beginners. Before buying an impact wrench, you should check the size of the drive that your unit is compatible with. Make sure to inspect the bolts and nuts that you are planning on working on to see if they have the right size for the model that you want to buy.

The weight of the tool

Determining the ideal weight of a wrench can be quite tricky. On one hand, you want the unit to be made from durable materials and have a certain density to it, on the other, you want it to be light enough to allow for a wide range of movement as well as lengthy periods of work without causing discomfort and hand tiredness. The key here is to get an impact wrench that is right at the sweet spot where the tool can provide an adequate amount of mobility and durability without leaning too much in one direction or the other.

Type of the battery

If you have any experience working with cordless tools, then you are probably aware that not all types of batteries are equal. The two main options that you will encounter on the market are nickel-cadmium batteries and lithium-ion batteries. The former is substantially cheaper while the later runs longer and charges much faster.


This is an absolute must. Regardless of how well-engineered a power tool is, malfunctions and other hosts of issues are bound to occur. That is why it is imperative to check the warranty before making a decision.

Extra features

Power tools these days come with a wide assortment of extra features that offer a lot of convenience and practicality. Some of these include Led lights that help you work in dark areas and the multispeed switch that affords you the luxury of picking a higher speed when you are doing high-volume applications or a lower one when you are trying to save battery life.

The advantages of using a cordless impact wrench over other tools

  • Extra power: As previously stated, the torque that is generated by impact wrenches is substantially higher than that of regular drills. Thanks to this impressive power, you can expect to loosen any type of bolt in a quick manner and with little effort.
  • Portability: The mobility that is provided by cordless power tools is simply invaluable. While mobile wrenches come with some drawbacks of their own, you are still getting the convenience of being able to use the tool anywhere you want. As long as you go for models that are equipped with high-quality batteries, you will encounter little to no issues with cordless impact wrenches.
  • The impressive speed: Time is of the essence, this ring especially true for professional mechanics that have to meet tight deadlines and work on multiple projects at the same time. Impact wrenches will help you breeze through a high number of bolts in a fraction of the time that would take regular wrenches.
